SHUTTLE-BOBBIN HOLDER.

SpecificatiOno f Letters Patent.

Application filed May 17, 1913. Serial No. 768,264.

To all whom it may concern Be it known that I, ALBERT MANDEVILLE, acitizen of the United States, residing at Ware, in the county ofHampshire and State of Massachusetts, have invented a new and usefulImprovement in Shuttle Bobbin Holders, of which the following is aspecification.

This invention is an improvement in bobbin holding means for loomshuttles, and the object of the invention is to provide a simple andinexpensive device for the holding and positioning of the bobbin in theloom shuttle, preventing longitudinal movement of the bobbin in theshuttle and at the same time holding it in proper position relative tothe top and bottom of the shuttle.

The invention further consists in the novel features of constructionhereinafter described, pointed out in the claims and shown in theaccompanying drawings, in which, I have illustrated the holding devicefor holding one end of the bobbin.

In the drawings, Figure 1 is a side elevation, the position of thebobbin head being indicated by dotted lines. Fig. 2 is a perspectiveview of my improved bobbin holding means removed from engagement withthe shuttle. Fig. 3 is a perspective view of the retention plate. Fig. 4is a perspective view of the spring jaws.

In these drawings 1 represents an end member of a shuttle body the underside of which is recessed as indicated at 2 and upon the upper side, thebody is recessed as indicated at 3, a transverse bore A leading from onerecess to the other. Bobbin head holding jaws are formed of spring wire,said wire being bent to form a U-shaped frame 5, the bow portion ofwhich is adapted to fit snugly in the recess 2 of the shuttle body 1.The side members of this frame slightly converge toward their free endsand their free end portions are bent upwardly or at right angles to theframe 5 as indicated at 6. These upturned end portions are substantiallvtriangular in cross section thereby affording two adjacent fiat faces,thereby enabling these jaws to more securely grip the bobbin head. Aretention plate is formed by bending a piece of metal to the form of aU-shaped frame having the upper and lower parallel faces 7 and 8,respectively both of which are longitudinally slotted as shown at 9, andsaid plates are connected by the bow portion of the frame said bowportion forming a connecting vertical plate 10. The lower plate 8 isnotched upon oppositesides as shown at 11 and from said notches to itsfree outer end is enlarged or widened and fits snugly within the recess2 of the shuttlebody 1. A suitable bolt 12 passes through the bore ofthe shuttle body and through the slots 9 of the holding plate andsecures the parts together.

In assembling the parts together, the wire frame 5 rests upon theenlarged portion of the plate 8 while the jaws 6 extend in advance ofand parallel to the plate 10. As the sides of the frame 5 convergenormally lateral movement is provided for by said side members in therecess 2 to permit insere tion or removal of the bobbin head. A portionof the bobbin is shown in dotted lines and it will be readily understoodthat the head of the bobbin rests between and is grasped by the jaws 6of the frame 1, said head bearing upon the plate 10 of the retentionframe.

By means of this construction the bobbin can be properly positionedrelaat the same time longitudinal movement of 1 the bobbin in theshuttle is prevented.

What I claim is 1. The combination with a shuttle body having a recessin its lower face, of a U- shaped spring wire member adapted to fit insaid recess, said member having upright parallel jaws at its free end,and a U-shaped plate fitting over an end of said body, the bow portionof said plate resting parallel to the jaws of the spring frame andbetween said jaws and said shuttlebody.

2. The combination with an end portion of a shuttle, said portion havingupper and lower recesses, a U-shaped frame, the upper and lower membersof which fit respectively in said recesses, and a spring wire frame, thebow portion of which fits in the lower recess, the projecting portion ofsaid spring frame being bent to form spring jaws parallel to and spacedapart from the bow por- 3. The combination with an end portion sidemembers of the Wire frame having latof a shuttle having upper and lowerrecesses, eral play in said recess, as and for the pura U-shapedretaining plate having its side pose set forth.
